You simply have to go to Cabela's as close to closing time as you can, hang around, and hang around and get someone to let you take a couple pairs to the door, they will do it, the situation just has to be right. There has to be absolutely NO one else they need to help and be within 5 minutes of shutting down the joint. Right now the Post Falls store closes after dark, so you can get a couple pair in your hands, get the "sales associate" to carry a couple pair and go to the door. Focus on a car that's out in the parking lot a ways and see which one lets you read the plate or name tag the best, right at dark and before the parking lot lights show on the cars. This will really let you make the best decision on how to spend your money. I have a pair of Nikon Monarchs, and old pair of Leupold Wind Rivers, and for the third season now a set of Swaro EL rangefinder Bino's and this is how I have compared them all. Both the Nikon's and the Swaro's were bought in that manner described above at Cabelas. The wind rivers were purchased back in '95 at White Elephant.
When it comes to the ridiculous high dollar optics like I am lucky enough to currently have, the difference for me was the clarity between the the swaro, leica and Zeiss. I think the combo pair of Leica's is a better rangefinder than is mine, but the clarity of mine was far superior, FOR MY EYES, than was the Leica, and that was what I was really paying for.
